Re: av gas

but it costs horsepower...apparently i'm not the only one who has seen it on the dyno as others are posting it in this thread. it's not a good gas, it's a GREAT gas, but it won't produce as much horsepower as other gasses will.At the end of the day, the lowest octane your motor will run on without knocking or pinging will generally give you the most power, as long as you're comparing good quality gasses. some of the pump gasses are so full of ethanol and other add ins that even though they may be all the octane you need, they don't produce as much power because they don't burn as well.

It is great fuel but you need to supply more of it since it is aireated fuel. I used it in my drag car engines and it always GAINED me alittle power over inadequet pump fuel. But it is designed for airplanes that are up in thin air where the eingine needs more oxygen to run up there.On the ground, you dont need extra oxygen. Simply richen your carb and watch it burn the tires.Tractor engine pistons dont know if they are in a John Deere or a Altered drag car. Richen the fuel supply to gain the advantage since it has oxygen in it and thus runs leaner.
